An "unfortunate error" in subtitling led to Newcastle United being labelled "black and white scum" during the BBC's Match of the Day 2 programme.
Commentator Guy Mowbray said Liverpool's Daniel Sturridge had scored five goals against the black and whites.
But software confused the word "comma", spoken by a subtitler, and put "scum" into the on-screen text.
The BBC said the error was spotted and corrected immediately.
Football commentary is re-voiced for subtitles by someone known as a "respeaker".
A BBC spokeswoman said: "Our live subtitling service is normally very accurate and makes our content much more accessible, but there are times when unfortunate errors occur.
"On this occasion the error was spotted and corrected immediately."
